WIS 4-13-01 Issue 1 Specification for blast furnace slag cement for in situ lining of water mains

This specification defines the requirements for manufacture of materials, quality assurance application, testing, packaging, marking, workmanship and storage of blast furnace slag cement intended for the renovation of water mains, where the lime rich cement lining acts as a corrosion inhibitor for the iron water mains.


The document has not been reviewed for its continued currency since publication.

By the mid 1990’s cement mortar lining of watermains in the UK was replaced by epoxy or resin lining. There is no indication of a likely return to the cement mortar lining technique – compounded by rapidly diminishing UK supplies of blastfurnace slag.

The Standards Board concluded at its September 2023 meeting that this document should be archived.
